  • Richard Smith thinks this is interesting:

Why set the page's base font to 62.5 percent? It just so happens that 62.5 percent times 16 pixels (the normal size of text in most web browsers) equals 10 pixels. With 10 pixels as a starting point, it's easy to compute what other text sizes will look like on the screen. For example, 1.5em would be 1.5 x 10 or 15 pixels. 2em is 20 pixels, and so on—easy multiples of ten.
